Importing all modules in a CVS repo with git-cvsimport

Importing all modules in a CVS repo with git-cvsimport

[Alex Bennee]

Hi,

I'm wanting to import the entirety of a CVS repository into git rather
than an individual module. However every approach I've tried to do this
fails as the underlying cvsps tool seems to only be able to deal with
modules rather than the whole project.

Is there any invocation I could do that would do the whole import?

A for loop? I don't think it's possible to treat the modules as just 
subdirectories, but you can loop over the modules, importing each of them 
into a separate git repository and then, if you want, merge each of them 
into a new master repository with the "subdirectory" strategy.

Unfortunately the repository is treated as one big ode dump place so I
don't want to loose the information about changes across many
dirs/modules. I shall try the "fakeing up" approach mentioned
elsewhere and see where that gets me.

What do you want the result to look like? If you have CVS modules 'foo',
'bar', and 'baz', I assume you want a repository with subdirectories
'foo', 'bar', and 'baz'?

In that case, you can create a CVS module that just includes all three:

  cd /path/to/cvsroot
  mkdir all
  cd all
  for i in foo bar baz; do
    ln -s ../$i
  done

and then:

  git cvsimport all

You might be able to do something similar with the CVSROOT/modules file,
but I haven't tried.

Hmm that fails:

test.cvs is a fresh checkout of the whole tree. "newcvs" is the root of
CVS on the server. The warnings are the same when I try with "." as the
module. Or where you saying do this with the actually CVS repo itself?

Hmm. I tested and it worked fine on my system. I'm not sure what you
mean by "the CVS repo itself." I actually linked within the $CVSROOT
hierarchy. If your version of CVS isn't happy with the symlinks for some
reason, you could just munge your cvs hierarchy (assuming you are just
doing a one-shot import):

  cd /newcvs
  mkdir all
  for i in `ls | grep -v all | grep -v CVSROOT`; do
      mv $i all
  done

You didnt' mention anything about you tried, but I recall that using ',' for 
the module name is possible. Some version of CVS do not like it however
and will bug out.

I tried:

git-cvsimport -v  -C /export/csrc/import_test/test.git -d $CVSROOT .
git-cvsimport -v  -C /export/csrc/import_test/test.git -d $CVSROOT ,

as well as the suggested ln -s tricks and none worked. I've now got a
copy of the actual repo from the cvs server so I'll try and fake up a
"supermodule" to contain the tree.

Any pointers always appreciated :-)
